What to do when a guppy is about to give birth
Guppies are a popular species among tropical ornamental fish, and their breeding process has attracted much attention from enthusiasts. Recent discussions on the entire network about guppies giving birth mainly focus on the following hot topics: signs of labor, prenatal preparation, production environment optimization and postpartum care. This article will combine the popular content of the past 10 days to provide structured solutions for aquarists.
1. Recognition of signs of labor in guppies

According to recent breeding forum data, the following are the typical characteristics of guppy giving birth:
| Type of sign | Specific performance | Appearance time |
|---|---|---|
| abdominal changes | The abdomen is distended and square, and the fetal spot is obviously blackened. | 24-48 hours before labor |
| Abnormal behavior | Hiding in corners, loss of appetite, slow swimming | 12-24 hours before labor |
| Cloacal dilation | The anus protrudes white | 6-12 hours before labor |
2. Key points in preparing the prenatal environment
A recent popular video on Douyin shows that the following preparations are required for a successful guppy delivery:
| Prepare project | Standard parameters | Things to note |
|---|---|---|
| Isolation tank setup | Water temperature 26-28℃, volume ≥10L | Need to provide water 3 days in advance |
| Placement of shelter | Aquatic plants/propagation box coverage reaches 40% | Avoid sharp decorations |
| water quality management | pH value 6.8-7.2, ammonia nitrogen ≤0.02mg/L | Tested 2 times a day |
3. Precautions during production process
Based on the latest discussion thread on Baidu Tieba, it is recommended to take the following measures:
1.Keep the environment quiet: Sudden lighting changes or loud noises may cause dystocia
2.Moderate feeding: Stop eating on the day of delivery and feed hatched brine shrimp 6 hours after delivery.
3.Emergency treatment: In case of childbirth, the water temperature can be increased by 1-2°C to stimulate production.
4. Key data for postpartum management
| Manage projects | 0-24 hours after delivery | 24-72 hours after delivery |
|---|---|---|
| Female fish feeding | High protein feed (3 times a day) | Regular feed (2 times a day) |
| Juvenile fish survival rate | 85%-92% (ideal environment) | Need to be raised in separate tanks |
| Water change frequency | No water changes allowed | Change water 10% daily |
5. Solutions to common problems
Based on recent popular questions and answers on Zhihu, we have compiled strategies for dealing with high-frequency questions:
1.Female fish eats small fish: Immediately transfer the female fish and isolate it in a special breeding box
2.Young fish do not open their mouths: Feed sewage water or egg yolk water (it takes 2 hours to clean up the remaining bait)
3.postpartum infection: Add 0.1% salt bath and maintain the water temperature at 28°C for observation.
6. Sharing of advanced skills
Recent suggestions from popular UP owners at Station B: You can pass the recordProduction logOptimize reproduction efficiency, including: production duration, number of young fish, abnormal conditions and other parameters, and establish individual reproduction files. Data shows that farmers recorded by the system can increase the survival rate of juvenile fish by an average of 15%.
Through the above structured plan, combined with the latest experience shared by the breeding community recently, the success rate of guppy reproduction can be effectively improved. It is recommended that novice breeders focus on the two key aspects of water quality monitoring and postpartum isolation.
